The first thing to take into account abourt padel court foundation is the planimetry of the floor. This is one of the most important points since it must be a completely homogeneous surface without potholes or holes since this will affect 3 important points of its installation and about padel court floor material.
Problems in the installation of the structure and glass
Problems in the evacuation of water when it rains and the formation of puddles
Problems in the quality of the game causing the ball to bounce poorly
When installing a paddle tennis court there are two possible solutions: use porous concrete or a semi-polished or floated concrete slab. Both options are good, but in this post, we want to explain the differences and which would be the best option to choose in each case.
If we are in an outdoor environment with no nearby paving. Padelmagic recommends a semi-polished concrete slab with a maximum lateral slope of 0.5% for the evacuation of rainwater, this being a perfect option due to durability, price and speed.
If we are in an outdoor environment that is completely level or that allows us to collect rainwater. Padelmagic would project a porous concrete slab where we maintain the planimetry and height of the entire adjoining area and the perfect collection of rainwater by draining the porous surface.
The perimeter strap where we must anchor the structure of the court must not be less than 30x30cm. (40x40cm is recommended) and the appropriate concrete for foundations (HM-25/20MM) with its corresponding reinforcement.
The slab (playing area) must have between 15 and 18 cm of concrete and its corresponding reinforcement.
If you choose the porous concrete option, it must have a perimeter ring (where we will anchor the structure) and a slab (play area).
Composition of the floor or playing area, from bottom to top:
− Compacted base, whether natural or selected gravel, type Z2 or equivalent, until having a compaction of 96% of the modified Proctor.
− Artificial gravel to form evacuation slopes.
− HM-25 concrete slab with slope for water evacuation.
− Drainage pipe. If the gable slab is executed, the slopes will be made towards the sides of the track. In this way, for slopes of 1% the distance between the highest point (longitudinal central axis of the court) and the lowest point (bands) will be 5cm, making it imperceptible for the players. All these elements make up what is called subbase, whose construction. It is super important to obtain a padel court in optimal playing conditions.
− Drainage layer: 8 to 20 cm of draining gravel.
− The slab will be finished with a porous pavement of at least 12cm, with an edge made on site with selected light gravel and cement mortar, spread and leveled to obtain the necessary slopes for the evacuation of water in the case of horizontal drainage.
SEMI-POLISHED CONCRETE SLAB
It is possible to execute the slab with a minimum measurement of 21 m long x 11 m wide, using a perimeter formwork, 6 mm mesh or fiber and concrete (HM-25/20MM), creating a uniform plate with a thickness Approximately between 12 and 15 cm, flat and at the level where the structure of the paddle tennis court can be placed and anchored.
If we give it a slope for the evacuation of water, this will always be less than 0.5% on one side. The final surface finish will be semi-polished with a helicopter, to prevent the grass from slipping.
The conduits for lighting wiring can be embedded inside the slab or in perimeter trenches that carry the lighting wiring to the register or protection box, leaving the register next to the light posts. Excavated trenches must be filled or covered with a lid to prevent falls.
